3 Claims. (01. 1 60-185) This invention relates tonew and usefulimprovements in garage doors and more particularly to the overheadopening type.

The principal object of the present invention is to provide an improvedgarage door, which Figure 6.

by a simple movement can be elevated to an outof-the-Way position.

Another important object of the invention is s Figure 2 is a fragmentaryvertical section taken I J on the line 2-2 of Figure 1.

Figure 3 is a fragmentary vertical sectional view taken alsosubstantially on the line-2--2 of Figure 1, but showing the door inpartly folded position.

Figure 4 is a vertical sectional view also taken substantially on theline 2-2 of Figure 1,but showing the door in fully opened position.

Figure 5 is an enlarged fragmentary detailed sectional view taken on theline 5-5 of Figure 3.

s Figure 6 is a fragmentary vertical sectional view through one of theslides and channeled guides.

Figure 7 is a fragmentary perspective view showing the lower portionofone of the channeled guides. s s

Figure 8 is a fragmentary detailed sectional view between the door frameand door showing the pivottherefor.

Referring to the drawings wherein like nua merals designate like parts,it can be seen that numeral 5 denotes a garage having a door frame madeup of side portions 6, 6 and "a top portion divided into a pair ofsections hingedly secured l 1. Numeral 8 generally refers to theimproved door which consists of an upper section 9 and a lowersectionulfl, these sections being hingedly secured together as at H. i

Suitable handles or the like I2 are provided on the lower outsideportion of the section II). and this sectionof the door has laterallydisposed pintles l3 which swivelly connect to blocks I4, slidablydisposed within the lowerportion of a vertically disposed and channeledguide [5. The lower portion of each of these guides l5 has a laterallydisposed member IGapertured to receive a pivot element I! which isdisposed into the corresponding frameside portion 6.

The upper section 9 has laterally disposed pintles I8 on which swivellymounted slides l9 are provided and these slides also operate in. thechanneled guide 1-5, as in the manner shown in At the upper edge ofsomesuitable heavy material 2|. I

The lower portion of this box 20 has a metal socket 22 at each endthereof to receive ;a pintle s 23 projecting from a supporting plate 24suitably secured as at 25 to the corresponding frame side portion 6.Thus the upper portion of the door section 9 is fixed as far asbeingmovable in a vertical direction, however, the upper section isallowed toswing to the extent shown in Figure 4.

Obviously, a slight pressure at the hingedlconnection between the doorsections 9, ID will move the sections to substantially the positionshown inFigure 3, after which a pull upwardly on the handles I2 willbringthe door sections to the ele-.

vated positions shown in Figure 4 in a quick and substantiallyeffortless operation. I While the foregoing specification sets forth theinvention in specific terms, it is to be understood that numerouschanges in the shape, size and materials may be resortedto withoutdeparting from the spirit and scope of the invention as claimedhereinafter.

Having described the claimed as new is:

1. A garage door comprising a door proper invention, what is together, apair of channeled guides one at each side of the door, pintlesprojecting laterally from the door sections andslides on the pintlesriding in the channeled guides, and counterbalancing means at the upperportion of the upper sec in the channeled guides, and counterbalancingmeans at the upper portion of the upper section,

said channeled guides being swingably supported at theirlower endportions.

3. A garage door comprising a (1001 proper di-j vided into a pair ofsections hingedly secured together, a pair of channeled guides one ateach side of the door, pintles projecting laterally from the. doorsections and slides on the pintles riding in the channeled guides, and.counterbalancing means at the upper portion of the upper sec-. l, j

tion, and means for swingably supporting the upper portion of the uppersection along with its the door section 9 is as counterweight, which maybe a box Zllfilled with
